Only those who frequently suffer from an upset stomach, constipation, and irregular bowel movements understand the importance of maintaining a healthy gut. While eating fibre-rich foods, staying hydrated, and engaging in regular physical activity can prevent gastrointestinal issues, kombucha, a fermented, sweet drink, can also ease digestive problems. Speaking with the OnlyMyHealth team, Dr Edwina Raj, Head of Services, Clinic Nutrition and Dietetics, Aster CMI Hospital, Bengaluru, shared how it can be prepared and the health benefits it holds, particularly for stomach ailments.

What Is Kombucha?
Kombucha is a beverage that is prepared by fermenting tea and sugar with a symbiotic culture of bacteria and yeast known as SCOBY, said Dr Raj.
According to the doctor, this drink can be prepared from various types of tea, like green, red, white, black, or oolong tea.
“As it contains beneficial bacteria that alter your gut health by fighting against the harmful microorganisms harboured in the intestine, it aids in improving the gut flora,” she explained.
Kombucha For Irritable Bowel Syndrome (IBS)
Irritable Bowel Syndrome (IBS) is a common gastrointestinal disorder that affects around 11% of the population globally, as per a study published in Dovepress.
The fermentation process involved in the making of kombucha helps in the production of probiotics, which in turn alleviates gastrointestinal symptoms associated with IBS, according to a 2019 study published in the Journal Nutrients.
Some of the common IBS symptoms include abdominal pain or discomfort, which is typically relieved by bowel movements. Additionally, one may experience changes in bowel habits, such as bloating, diarrhoea, constipation, or a combination of both.
Kombucha For Constipation
Emerging studies also suggest that probiotics can improve the symptoms of constipation, such as straining, incomplete evacuation, and stomach ache, Dr Raj noted.
In a 2017 review of 475 articles published in the Archives of Gerontology and Geriatrics, researchers found that some probiotics might be helpful for constipation in elderly people. They saw a 10–40% improvement compared to those who didn't take probiotics. However, the research investigates the benefits of probiotics in general and does not directly discuss kombucha.

Other Benefits And Health Risks
Apart from providing digestive health benefits, kombucha also provides nutrients such as organic acids, amino acids, vitamins, minerals, and polyphenols. This sweet, acidic drink is also a potent source of antioxidants and anti-inflammatory agents, which are claimed to reduce the risk of cancer.
However, Dr Raj said, “There are reported concerns about the toxicity and detrimental effects on health, particularly for immune-compromised individuals. The adverse effects include nausea, dizziness, vomiting, allergic reactions, and headaches.”
He added, “Excessive intake of kombucha can lead to lactic acidosis, which is an acid accumulation in the blood, especially among those with compromised immunity, heavy alcoholics, children, and pregnant women.”
Conclusion
Kombucha tea is known for its probiotic content, which is thought to support gut health. Studies have claimed that it can relieve symptoms of IBS and ease constipation. However, scientific evidence on its specific benefits is limited, and individual reactions vary. In certain cases, toxicity from excess kombucha intake can also cause other side effects. Therefore, caution and moderation are advised, especially for those with pre-existing health conditions.
